Q6 Cross-reference

Figure 1 presents the scatter distribution of country’s life expectancy and GDP per capita. We can observe a positive correlation between life expectancy and GDP per capita. Figure 2 presents the top 10 countries with highest life expectancy. We can observe Macao SAR, China has the highest life expectancy. Figure 3 presents the top 10 countries with highest GPD per capita. We can observe Lienchtenstein has the highest GDP per capita. Table 1 presents the statistics of countries with the highest life expectancy and the highest GDP per capita.
